It's actually a small class which mimics  teh LVM behavior.

It was written from scratch - and is still rough. But the idea works out.
It is intended to be used with python-mock.

The module is here:
https://gerrit.ovirt.org/gitweb?p=imgbased.git;a=blob;f=tests/fakelvm.py;hb=HEAD

One consumer of this is:
https://gerrit.ovirt.org/gitweb?p=imgbased.git;a=blob;f=tests/testSanity.py;hb=HEAD

The biggest gap is to document it and get the API straight.

I.e. currently I tried to follow the following pattern:

lv = LV()  # To instantiate a LV
lv = VG().create(…)  # To create a mocked VG
